- the oxidizing gas phase that can be implemented during step a) consists of air.
- the treatment temperature imposed during step a) may be between 900 ° C and 1000 ° C.
- the acidic liquid medium used in step b) is in the form of an aqueous solution.
- the acidic liquid medium may comprise a mixture of hydrofluoric acid and nitric acid.
- the interphase layer may be a layer of boron nitride or pyrolytic carbon.
- the interphase layer is preferably a boron nitride layer.
- a plurality of silicon carbide fibers each having an oxygen content of less than or equal to 1% atomic percentage can be processed.
- the present invention also relates to a process for manufacturing a fibrous preform comprising at least one step of treating a plurality of silicon carbide fibers by implementing a method as described above and a step of forming a fiber preform. a fiber preform by implementing one or more textile operations from said plurality of fibers thus treated.
- the present invention also relates to a process for manufacturing a fibrous preform comprising at least one step of forming a fibrous preform by implementing one or more textile operations from a plurality of silicon carbide fibers exhibiting each an oxygen content less than or equal to 1% atomic percentage and a processing step of said plurality of fibers, once the preform formed, by carrying out a method as described above.
- the present invention also relates to a method of manufacturing a composite material part comprising at least one step of manufacturing a fiber preform by implementing a method as described above followed by a forming step of at least one carbon matrix phase or a ceramic material densifying said fiber preform.

- the invention relates to the treatment of silicon carbide fibers having an oxygen content of less than or equal to 1% atomic percentage.
- the invention therefore relates to the treatment of silicon carbide fibers relatively low in oxygen, these fibers being distinguished from Si-C-0 fibers which have an oxygen content outside the range mentioned above.
- the fibers treated by the process according to the invention may, for example, have a C / Si atomic ratio of between 1 and 1.1, for example between 1 and 1.05.
- Silicon carbide fibers called third generation, as the type of fibers "Hi-Nicalon S" have such an atomic ratio and an oxygen content less than or equal to 1% atomic percentage.
- Other types of silicon carbide fibers can be treated by the process according to the invention as "Hi-Nicalon" type fibers which have a C / Si atomic ratio outside the ranges mentioned above but which have a negative oxygen content less than or equal to 1% atomic percentage.
- Figure 1A illustrates very schematically the section of a silicon carbide fiber 10 having an oxygen content less than or equal to 1% atomic percentage before implementation of the method according to the invention.
- the silicon carbide fiber 10 consists of a silicon carbide core 12 and a surface layer 11 located in the vicinity of the surface of the fiber 10.
- the surface layer 11 has a surface state and a composition heterogeneous and in particular comprises carbon and at least one silicon oxycarbide.
- the surface layer 11 is responsible for a decrease in the quality of the adhesion of the fiber to the interphase layer.
- the thickness e 1 of the surface layer 11 may typically be greater than or equal to 1 nm, for example at 5 nm, for example at 10 nm.
- the surface layer 11 is intended to be eliminated by implementing the method according to the invention.
- Silicon carbide fibers may be processed in any form, for example, yarns, tows, strands, cables, fabrics, felts, mats and even two- or three-dimensional preforms.
- the silicon carbide fibers treated according to the process of the invention may advantageously be used for producing fiber preforms of composite material part.
- a fibrous texture may first be obtained by carrying out one or more textile operations and then this fibrous texture may be shaped in order to obtain a fibrous preform having the desired shape.
- the fibrous texture can be obtained by three-dimensional weaving, for example "interlock" weave, that is to say a weave weave in which each layer of weft threads binds several layers of warp threads with all the threads of the same column of weft having the same movement in the plane of the armor.
- Other types of three-dimensional weaving may of course be used to make the fibrous texture.
- the weaving can be performed with warp yarns extending in the longitudinal direction of the texture, being noted that weaving with weft yarns in this direction is also possible.
- Various modes of weaving that can be used to produce the fiber texture are described in particular in document WO 2006/136755.
- the fibrous texture may be further formed by assembling at least two fibrous structures.
- the fibrous structures can be bonded together, for example by sewing or needling.
- the fibrous structures may in particular be each obtained from a layer or a stack of several layers of:
- UD Unidirectional web
- nD multidirectional webs
- the silicon carbide fibers can be treated by the process according to the invention before or after the production of the preform.
- the silicon carbide fiber 10 having an oxygen content of less than or equal to 1 atomic percent is first contacted with an oxidizing medium. Following this contacting, the surface layer 11 is oxidized and is converted into a silica layer 22 having a thickness e 2 which, in the example illustrated, is substantially equal to the thickness e 1 of the surface layer 11 (see FIG. Figure 1B).
- the thickness of the silica layer formed may, alternatively, be greater than the thickness of the surface layer 11.
- the fiber 10 may be brought into contact with an oxidizing gas phase comprising the element O.
- the fiber 10 may, during step a), be brought into contact with air or steam of water.
- the treatment of the fiber 10 with the oxidizing gas phase can be carried out at a treatment temperature of between 600 ° C. and 1000 ° C., for example between 800 ° C. and 1000 ° C., preferably between 900 ° C. and 1000 ° C. ° C and 1000 ° C.
- the treatment carried out during step a) can be carried out at atmospheric pressure or at a pressure below atmospheric pressure.
- step a) can be carried out under atmospheric pressure by treating the fiber 10 with an oxidizing gas phase by imposing a treatment temperature of between 600 ° C. and 1000 ° C.
- the silicon carbide fiber may be brought into contact with the oxidizing medium during step a) for a duration greater than or equal to 1 minute, for example 5 minutes, for example 10 minutes, for example 30 minutes, this duration being for example between 5 minutes and 60 minutes.
- the silica layer 22 obtained it is then removed in step b) by dissolution by contact with an acidic liquid medium comprising at least hydrofluoric acid.
- the acidic liquid medium used during step b) may, for example, be in the form of an acidic aqueous solution.
- the acidic liquid medium is in the form of an aqueous solution comprising at least hydrofluoric acid.
- the hydrofluoric acid concentration in the acidic liquid medium may advantageously be greater than or equal to 0.5 mol / l.
- the acidic liquid medium may be in the form of an aqueous solution comprising at least one mixture of hydrofluoric acid and nitric acid.
- the concentration of hydrofluoric acid in the acidic liquid medium may advantageously be greater than or equal to 0.5 mol / L and the concentration of nitric acid in the medium acidic liquid may advantageously be greater than or equal to 0.5 mol / L.
- the concentration of nitric acid in the acidic liquid medium may for example be between 0.5 mol / L and 5 mol / L.
- the temperature imposed during step b) may be between 10 ° C and 100 ° C, for example between 10 ° C and 40 ° C.
- the duration of contacting the fibers with the acidic liquid medium during step b) can by for example, be greater than or equal to 1 minute, for example 5 minutes, for example between 5 minutes and 60 minutes.
- FIG. 1C shows the result obtained after implementing steps a) and b). It is in this case obtained a silicon carbide fiber having a surface state and a homogeneous composition. In the example illustrated, after step b), the entire surface layer 11 is eliminated without substantially affecting the core 12 of the fiber. After completion of steps a) and b), a fiber 12 having a surface of pure silicon carbide is obtained. This result is clearly distinguishable from the result that would be obtained in the case where a silicon carbide fiber having an oxygen content greater than 1% in atomic percentage (for example a "Nicalon" fiber) was treated with an acidic liquid medium comprising by a mixture of hydrofluoric acid and nitric acid.
- an acidic liquid medium comprising by a mixture of hydrofluoric acid and nitric acid.
- the fact of succeeding in etching the surface of the silicon carbide fibers by the treatment according to the invention is related to the implementation of silicon carbide fibers having an oxygen content of less than or equal to 1 % atomic percentage.
- the interphase layer is then deposited in contact with the surface of the fiber obtained after implementing steps a) and b).
- the deposition of the interphase layer directly on the surface of the fiber is carried out in a manner known per se.
- the fiber treated by the process according to the invention has an improved bond with the interphase layer.
- the interphase layer may be a boron nitride (BN) layer or a pyrolytic carbon (PyC) layer.
- the thickness of the interphase layer may for example be greater than or equal to 200 nm, for example between 200 nm and 300 nm.
- One or more additional layers may be deposited on the interphase layer, for example made of ceramic material such as SiBC, BNSi or silicon carbide.
- a plurality of silicon carbide fibers each having an oxygen content of less than or equal to 1% atomic percentage can be processed simultaneously by the method according to the invention.
- a piece of composite material with improved mechanical properties can then be formed by densifying, by at least one matrix phase, a fiber preform comprising the treated fibers coated with the interphase layer.
- the fibrous preform forms the fibrous reinforcement of the composite material part and the matrix phase is formed in the porosity of the fibrous preform.
- the matrix phase may for example be silicon carbide or carbon.
- the densification of the fiber preform can thus be carried out by a liquid route (impregnation with a precursor resin of the matrix and transformation by crosslinking and pyrolysis, the process being repeatable) or by a gaseous route (chemical vapor infiltration of the matrix).
- the invention is particularly applicable to the production of ceramic matrix composite material (CMC) parts formed by a fibrous reinforcement of silicon carbide fibers densified by a ceramic matrix, in particular carbide, nitride, refractory oxide, etc.
- CMC ceramic matrix composite material
- Typical examples of such CMC materials are SiC-SiC materials (reinforcement of silicon carbide fibers and silicon carbide matrix).
- the matrix phase can also be carried out by infiltration of silicon in the molten state (“Melt-Infiltration" process).
- Hi-Nicalon S type fibers were contacted with an oxidizing gas phase consisting of air by imposing a treatment temperature of 650 ° C for a treatment time of 45 minutes. Such treatment has chemically transformed the surface of the fibers to form a layer of surface silica. Secondary ion mass spectrometry (“SIMS”) analysis provided an estimate of the thickness of the silica layer thus formed. The thickness of the silica layer has thus been estimated at 1.6 nm.
- SIMS Secondary ion mass spectrometry
- Oxidized fibers having a surface silica layer were then divided into five groups and each group of fibers was subjected to a treatment using a different acid solution. All acid treatments were done by dipping the fibers into a bath of the acid solution for one hour at a temperature of 30 ° C.
- the compositions of the five acid solutions that have been used are listed below:
- An interphase layer of boron nitride was then formed on the fibers obtained by carrying out the oxidation described above followed by the acid treatment with the hydrofluoric acid solution at 448 g / L.
- the interphase layer of boron nitride was formed directly on the surface of the silicon carbide fibers by implementing the following operating conditions:
- FIG. 2 shows a photograph of the result obtained. Good cohesion is observed between the fibers and the interphase layer of boron nitride.
- the coated fibers thus obtained constitute a fibrous reinforcement for a piece of composite material giving said part improved mechanical properties.
- Figure 3 is provided for comparison and shows that when the processing of Steps a) and b) according to the invention is not performed, there is a decohesion between the fibers and the boron nitride interphase layer. This decohesion results in a reduction in the mechanical properties of the composite material part formed from the fibers thus coated.
- step a) Another test was carried out under the same conditions as in Example 1 except that the oxidation of step a) was carried out by contacting the fibers with air at a temperature of 1000 ° C. during a treatment period of 15 minutes.
- the thickness of the silica layer formed in this case was estimated by secondary ionization mass spectrometry analysis about ten nanometers. After the treatment with the acid medium, the same surface state is obtained for the fibers as in Example 1 and consequently similar mechanical properties.
- FIG. 4 shows the results obtained during a tensile test between, on the one hand, a part obtained after treatment of the fibers by a process according to example 1 (curve I) and, on the other hand, a part obtained after treatment of the fibers. in the same manner as in Example 1 except that the prior oxidation treatment (step a)) was not performed (curve II). It can be seen that the fact of carrying out the treatment according to the invention advantageously makes it possible to very significantly improve the elongation at break of the part obtained.
